Hello together

Big question for the Command "DEVICE ws2812 w" command.

How to change or modify the timing as i use a different RGBW LED which have a very different T1H and T1L timing.

Is there any way?

Thanks for your help

Perhaps experiment with 'type' O, B ad S to see if one of them is better.

If it is to special and nothing helps,
you can program the interface by PIO.

Question about PIO DMA TX interupt
I post an example code for this. By using RGBWs the autopull-value should be changed to 32(0)!
